I don't...I would lose it for sure. Personally I do think it looks more professional, but only if it's the right size and you know how to wear it.
If you wear a hat because you like the way it looks, or for some other personal reason, cool corn man, go for it.
If you wear a hat because you think some delta pilot is going to see you in the terminal and think "hey that guy should work for Delta, I'm gonna give him a recommendation"....well...good luck with that
I literally had a conversation with an FO who told me he wears the hat because "he wants to get hired at delta". When I asked him how it would get him hired at delta, he had no answer. Just brainwashed.
Side note...is LA to Vegas coming back or did that get canxed?
